The general list of international standards for SDH Equipment is as follows:

ITU-T G.703

ITU-T G.707

ITU-T G.783

ITU-T G.957

ITU-T G.958

There are various other standards that could apply depending on the function of the Optical Product to be tested. Countries like Brazil, Japan, Switzerland, Poland, and Singapore have their own standards for SDH-type equipment. MET is able to test against these standards as well as vendor-driven requirements. Our GR-253-CORE testing capability, coupled with our existing capability to test fiber optic components to GR-326-CORE, GR-910-CORE, GR-1073-CORE, GR-1209-CORE and GR-1221-CORE allows MET to satisfy all testing aspects of your Optical Product.
